COLTER-HOLDER FOR PLOWS.

SPECIFICATION forming part of Letters Patent No. 446,452, dated February17, 1891.

Application filed October 29, 189i). Serial No. 869,726. (No model.)

T0 at whom it may concern:

Be it known that I, EDGAR M. IIIOKMAN, a citizen of the United States,residing at Albion, county of Calhoun, State of Michigan, have inventeda certain new and useful Improvement in Colter-I'Iolders for Flows; andI declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itpertains to make and use the same, reference being had to theaccompanying drawings, which form a part of this specification.

It is the object of my invention to produce a holder for the colter of aplow which shall be applicable to either a wooden-beam plow or aniron-beam plow, and by means of which the colter may be adjusted eitherhorizontally orvertically.

The invention consists in a combination of devices and applianceshereinafter described and claimed.

In the drawings, Figure 1 illustrates a plowbeam and colter with myattachment thereon. Fig. 2 is a detail view of the holder itself. Fig.is a detail view of the tie-plate. Fig. a is a detail view of the plateC.

In carrying out the invention, A represents the beam of the plow and Bthe colter.

C is a plate shaped on its upper surface so that it will fit the underside of either a Wooden or iron beam of a plowthat is to say, the faceis made flat and provided with a recess or groove 0, in which the rib onan iron beam may rest. Slots or openings 0 are provided through whichbolts D ext-end upward, where they are passed through slots or openingse in a tie-plate E, which fits across the top of the beam. Ext-endedfrom the plate C are the arms or flanges C, provided with orifices 0Between these flanges is a sleeve F held in place by the bolt G. Uponthe end of this sleeve is the arm F, provided in its end with the slotf. Extending through the orifice o is the bolt II, which also extendsthrough the elongated slot f, and is fastened upon the opposite end bynuts and washers. Sleeved upon the sleeve F is the arm J, pro-- videdwith set-screw j. This arm is prevented from revolving upon the sleeve Fby the spline or rib f and yet is movable lengthwise of the sleeve. Tothe arm J the colter-arm is attached. It will now be seen that by meansof my holder the colter may be adjusted in any direction; and the holderis applicableto any size or style of beam-that is to say, the arm .I ismovable along the sleeve. Consequently the colter is movablehorizontally. By means of the elongated slot and bolt II the sleeve Fmay be revolved, consequently raising or lowering the colter-point.

The slots in the plate and tie-plate, through which the fasteningbolts Dare passed, permit the holder to be attached to any-width beam, and thelength of the bolts of course determines the thickness of the beam.

\Vhat I claim isl. A colter-holder for plows, consisting of a plate C,an axially-rotatable sleeve F, suspended by the plate in a horizontalplane, means for locking the sleeve in position when axially rotated tothe desired position, and a colter-carrying arm J, connected by a splinewith the sleeve and adjustable along the length thereof, substantiallyas described.

2. In a colter-holder for plows, the combination, with the beam, of theplate C, attached thereto, the sleeve F, supported by the plate andprovided with an arm F, the end of said arm being adjustable vertically,and the arm J, engaged on said sleeve by the spline f, but adjustablelengthwise on the sleeve, substantially as described.

3. A colter-hold er for plows, consisting of a plate C, having pendentflanges C, a horizontal bolt G, supported by the flanges, a horizontalsleeve F, rotatable axially on the bolt and provided with means forlooking it in a fixed position, and a eolter-carrying arm J, connectedby a spline with the sleeve and adjustable along the length thereof,substantially as described.

In testimony whereof I sign this specification in the presence of twowitnesses.
